sorry I didn't notice this earlier...
Those are silent errors. I placed them in there when I was trying to get weird bugs to repeat. They are take care of in the end but, I was trying to figure out exact place where they happen.
The invalid procedure though... that is interesting. Do you have the log still? If you do please copy it here.

um... the log is clean... no issues there. You must have run it some time after getting that error. In fact the log tells me so... you posted on 5/15/2017 10:29 and the new log says 5/15/2017 19:26:11
again... Don't know how I missed seeing this post too.
